Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Results and discussion

Any other information on results incl. tables

During the cooling cycle of the first experiment (5.41 mg test substance in 40 uL aluminium crucible cooled at 5°C/min 30°C to -50°C), no transition was observed between 30°C and -50°C. During the heating cycle of first experiment (heated at 5°C /min from -50 °C to 30°C) no glass transition was observed. A repeat of the experiment with 9.995 mg in a 40 uL aluminium crucible also showed no phase transition over the same temperature range. A small wide exothermic peak was observed (-44 °C to -26 °C) in both heating experiments. This peak is considered not related to phase transition, as melting is an endothermic reaction. No metlting/freezing point could be established.

Applicant's summary and conclusion

Conclusions:
No melting point could be determined
Executive summary:

In a test using differential scanning calorimetry, no phase transitions were identified over a temperature range of -50 °C to 30°C. Therefore it is concluded that a melting point could not be determined for the test substance.
